BTB12H-600CW3G

Triacs Overview

The BTB12H-600CW3G is a logic level Triac manufactured by Littelfuse, designed for high-efficiency switching in AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 12 A. The device operates within a junction temperature range of -40 °C to +150 °C and utilizes a TO-220AB package for through-hole mounting. Key electrical characteristics include a gate trigger current (Igt) of 35 mA, a holding current (Ih) maximum of 50 mA, and a non-repetitive peak on-state current of 125 A. The typical on-state voltage drop is 1.55 V at rated current.

Triacs Feature Summary

• Logic level gate sensitivity enabling direct drive from microcontrollers or low-power logic circuits without additional amplification stages.
• High thermal stability supporting operation up to 150 °C junction temperature for robust performance in demanding environments.
• Flange-mountable TO-220AB package design facilitating efficient heat dissipation and secure mechanical installation.

Triacs Applications

• Solid-state relays requiring compact form factors and reliable AC load switching.
• Motor speed control systems for fans, pumps, and small appliances.
• Lighting dimmer circuits for residential and commercial LED or incandescent loads.

Triacs Procurement Notes

Verify the specific suffix 'CW3G' against the manufacturer's latest datasheet to confirm pinout configuration and packaging type. Ensure that the procurement channel provides original Littelfuse documentation to validate RoHS compliance and traceability. Cross-reference the part number with authorized distributors to avoid counterfeit components, as logic level Triacs are subject to strict quality controls.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 12 A continuous current capacity are required for AC phase control. The 35 mA gate trigger current makes it suitable for interfaces with standard TTL or CMOS logic outputs. Consider the TO-220AB package size for adequate thermal management without requiring excessive heatsinking in moderate duty cycle applications.

Triacs Part Context

This Triac belongs to the BTA/BTB H-series family, characterized by high current density and logic-level gate drive capabilities. The BTB variant typically denotes a specific internal structure optimized for lower gate charge compared to standard series. It serves as a solid-state alternative to electromechanical relays in AC switching applications where silent operation and long life are critical.

Triacs Replacement Considerations

Direct replacements include the BTA12-600CW3G, which shares identical electrical ratings and pinout configurations. Verify that substitute parts maintain the same 35 mA logic-level gate trigger specification to ensure compatibility with existing drive circuitry without modification.
